Response to Letter to the Editor: Impact of 1024-Matrix Size on Perforating Artery Visualization in Cerebral CTA Using a 64-Slice CT Scanner.

This response addresses a Letter to the Editor commenting on our article on 1024-matrix reconstruction for perforating artery visualisation in cerebral CTA using a 64-slice CT scanner (https://doi.org/10.1002/jmrs.70055). It acknowledges that integration with iterative or deep-learning reconstruction, workflow and PACS burden, and downstream clinical outcomes warrant further study, and emphasises that a targeted 1024-matrix strategy limited to clinically critical intracranial regions offers a practical compromise.
